Fuel tank
Fuel tanks should be made of appropriate material such as
(stainless) steel or plastic. Steel tanks should not be galvanized
or painted inside. Condensation can occur in metal tanks when
temperature changes. Therefore, water accumulates at the
bottom of the tank and provisions should be made for the
drainage of this water.
The tank will need a filling connection, a return connection and
an air ventilation connection which will require protection
against water entry.
Some official regulations do not allow connection points at the
base of the fuel tank; connections are to be made at the top of
the tank with internal tubing down to a few cm above the
bottom of the tank. When using the existing fuel tank of the
propulsion engine, fitting should be carried out with extra care.
Both a supply line and a return line should be installed and go
into the tank from the top. Interference of the two systems
(propulsion engine and genverter) should be avoided. Emptying
the tank below the level of the suction pipe of the genverter
could make it necessary to bleed the fuel system.

Fuel lift pump
All models are fitted with an external fuel lift pump. This should
be mounted close to the tank, in an angle or vertically to
prevent air bubbles from blocking the system. As the pump
makes clicking noises, it is recommended to use rubber
mountings. If the clicking noises of the pump are not
acceptable, a noiseless pump is available as an option (art. no.
50202200).

Fuel pipes
When the tank is above the genverter (Figure 7) we
recommend ending the return line on the top of the tank.
When the return is on the top, siphoning of the return line is
impossible in case of a leakage. Only the fuel supply line will
need to be fitted with a fuel cock. When the tank is below the
genverter (Figure 6) we recommend ending the return line on
the bottom of the tank below the inlet of the supply line. This
will prevent the fuel supply line from being drained into the
